Massive finger-vein identification based on local line binary pattern under parallel and distributed systems
(2019)
Massive individuals identification is a challenging problem in modern society. Particularly, finger-vein recognition is an emerging biometric technique with several advantages, especially in terms of security against ...
Teorías subjetivas de docentes sobre la implementación de los objetivos transversales en un contexto complejo
(2019)
Se presenta un estudio cualitativo sobre teorías subjetivas (TS) de docentes respecto a la implementación de los Objetivos Transversales (OT) en una comuna del norte de Chile. Las entrevistas se llevaron a cabo a través ...
Comparison of classification algorithms for the detection of bone weakness in students using anthropometric data
(2019)
Low bone mineral density can lead to weak and fragile bones that lead to problems of osteoporosis and fractures in people, early detection can help their treatment. This research compares five data mining algorithms to ...
Trivialización, predicado y nominalización
(2019)
El presente escrito tiene por objetivo discutir los alcances de la denominada vía predicativa en el análisis de la rigidez de los términos generales. En particular, se analizará la interpretación que Zerbudis (2013) realiza ...
Iris recognition based on displacementinformation using a sparse matching technique
(2019)
Iris recognition is one of the most promising fields in biometrics. During the image acquisition, images are affected by surrounding parts of the eye such as eyelids or eyelashes. Besides, deformations of the iris image ...
Evaluation of LBP-based descriptors for iris recognition based on learning vector quantization classifier under a multi-core platform
(2019)
In recent years, iris recognition techniques have focused the attention on the biometric area. Particularly, the performance of an iris recognition system depends on the representation of the texture of the images. In this ...
Cosmology in cubic and f(P) gravity
(2019)
We construct cubic gravity and its f(P) extension and we investigate their early- and late-time cosmological applications. Cubic gravity is based on a particular invariant P, constructed from cubic contractions of the ...
BTZ black hole with Korteweg–de Vries-type boundary conditions: thermodynamics revisited
(2019)
The thermodynamic properties of the Bañados-Teitelboim-Zanelli black hole endowed with Korteweg–de Vries (KdV)-type boundary conditions are reconsidered. This family of boundary conditions is labeled by a non-negative ...
Contribution of sleep deprivation to suicidal behaviour: a systematic review
(2019)
Sleep disturbances and suicidal behaviour are highly prevalent phenomena, representing with a significant burden to society. Sleep has been acknowledged as a potential biomarker for suicidal behaviour. Over the past decade ...
Onset of schizophrenia diagnoses in a large clinical cohort
(2019)
We aimed to describe the diagnostic patterns preceding and following the onset of schizophrenia diagnoses in outpatient clinics. A large clinical sample of 26,163 patients with a diagnosis of schizophrenia in at least one ...
